DETAILED DESCRIPTION

[0050] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0051] An automatic feeder is a device that automatically adds materials to a processing unit. Compared with traditional manual feeding, it has a higher degree of automation, and the feeding efficiency and delivery position accuracy are also relatively high. Most feeders on the market can only realize the feeding process of parts of a single size. With the continuous updating of personalized products, the existing feeder structure cannot adapt to the automatic transmission of parts of multiple varieties and varying sizes, and its structure is relatively complex and the manufacturing cost is high. The present invention mainly provides an automatic feeding device to solve the above two problems, which can effectively solve the two common problems of the above traditional feeders.

[0052] like Figure 1 As shown, an automatic feeding device of the present invention comprises: a support base 10, a material storage mechanism 20, a material pushing mechanism 30, a material feeding mechanism 40 and a mechanical arm assembly 50.

[0053] like Figure 2 and Figure 3 As shown, the material storage mechanism 20 is fixedly mounted on the support base 10 .

[0054] A storage box 21 is provided on the upper part of the storage mechanism 20, and the inside of the storage box 21 is used to place the workpiece 60 to be processed. A push hole 211 is provided at the bottom of the storage box 21, and the push mechanism 30 pushes the workpiece 60 in the storage box 21 through the push hole 211. A discharge port 212 is provided on one side of the storage box 21, and an adjustable valve 213 is movably provided on the discharge port 212. Preferably, a valve cylinder 214 is provided on the upper end of the valve 213 to drive the movement of the valve 213, and the expansion and contraction amount of the valve cylinder 214 is adjusted according to the size of the workpiece 60 to control the size of the discharge port 212. The setting of the push mechanism 30 can make the installation angle of the storage box 21 have more options.

[0055] As a preferred solution of the present invention, a mounting frame 215 is provided on the upper part of the discharge port 212 , the mounting frame 215 is fixed to the outer side of the storage box 21 , and the valve cylinder 214 is detachably mounted on the mounting frame 215 .

[0056] A triangular support frame 22 is provided at the lower end of the material storage box 21. The triangular support frame 22 can not only raise the material storage box 21 to reserve an installation position for the material pushing mechanism 30, but also increase the stability of the material storage box 21.

[0057] A material blocking assembly 23 is also provided at the discharge port 212 of the material storage box 21, and a material blocking groove 231 is formed between the material blocking assembly 23 and the discharge port 212. When the valve cylinder 214 is actuated to open the discharge port 212 so that a workpiece 60 can leave the material storage box 21 under the action of the pushing mechanism 30, the material blocking assembly 23 blocks the workpiece 60 from continuing to move in the direction away from the material storage box 21. At this time, the valve cylinder 214 is actuated again to close the discharge port 212 to prevent other workpieces 60 in the material storage box 21 from rolling out of the material storage box 21.

[0058] A baffle 232 is provided at the upper end of the baffle assembly 23, and a baffle cylinder 233 is provided at the lower end of the baffle 232. The baffle cylinder 233 controls the lifting and lowering of the baffle 232. When the baffle 232 rises, the workpiece 60 is blocked in the baffle groove 231 by the baffle 232. When the baffle 232 descends, the workpiece 60 enters the feeding mechanism 40.

[0059] An adjusting screw 234 is provided on one side of the baffle cylinder 233 close to the material storage box 21, and the adjusting screw 234 is fixed on the support base 10. The adjusting screw 234 is used to adjust the distance between the baffle 232 and the material storage box 21, thereby indirectly adjusting the width of the baffle groove 231. When the diameter of the workpiece 60 is large, the adjusting screw 234 can be rotated in the direction away from the material storage box 21 to increase the width of the baffle groove 231. When the diameter of the workpiece 60 is small, the adjusting screw 234 is rotated in the direction close to the material storage box 21, and the width of the baffle groove 231 is reduced.

[0060] Preferably, a conversion block 235 is provided between the baffle cylinder 233 and the adjusting screw 234. The function of the conversion block 235 is to convert the rotation of the adjusting screw 234 into the horizontal movement of the baffle cylinder 233. Preferably, the baffle cylinder 233 can be fixed on one side of the conversion block 235, and an internal thread compatible with the adjusting screw 234 is provided at the place where the conversion block 235 is connected to the adjusting screw 234, so that the above-mentioned goal can be easily achieved.

[0061] As another preferred embodiment of the present invention, a rotating handle 236 is provided at the end of the rotating adjusting screw 234, and a dust cover 237 is provided on the outside of the adjusting screw 234. The rotating handle 236 can make the adjusting screw 234 rotate more conveniently, and the dust cover 237 can ensure that the adjusting screw 234 can be protected from the interference of dust in the external working environment.

[0062] The pushing mechanism 30 includes a pushing bracket 31 , a pushing cylinder 32 , a limiting rod 33 and a limiting block 34 .

[0063] The material pushing bracket 31 is rotatably mounted on the triangular support frame 22 and can push the workpiece 60 away from the material storage box 21 in the material storage box 21 through the material pushing through hole 211 .

[0064] Preferably, one end of the pushing bracket 31 is fixed to the lower end of the storage box 21 by bolts, and the other end of the pushing bracket 31 is provided with a pushing block 311 and an arc-shaped blocking block 312, so that when the pushing block 311 pushes the workpiece 60, the blocking block 312 can block other workpieces 60 from moving in a direction away from the storage box 21, so that it can be better achieved that only one workpiece 60 leaves the storage box 21 when the discharge port 212 is opened.

[0065] The locking cam 331 is engaged with the locking cam 332 and is then engaged with the locking cam 332 to lock the locking cam 333. When the locking cam 332 is engaged, the locking cam 332 is engaged with the locking cam 333.

[0066] The feeding mechanism 40 is installed on one side of the material storage box 21 where the material outlet 212 is provided and is fixed on the support base 10. The feeding mechanism 40 includes a workpiece support base 41 and a feeding cylinder 42. Both the workpiece support base 41 and the feeding cylinder are installed on the support base 10. The workpiece support base 41 is used to receive the workpiece 60, and the feeding cylinder 42 is used to push the workpiece 60 on the workpiece support base 41 toward the robot arm assembly 50. When the baffle cylinder 233 controls the baffle 232 to descend, the workpiece 60 moves to the upper end of the support base 41, and the feeding cylinder 42 is activated at this time to push the workpiece 60 toward the robot arm assembly 50.

[0067] like Figure 1 and Figure 4 As shown, the robot arm assembly 50 includes a robot arm bracket 51 , a crossbeam 52 , a vertical moving guide rail 53 , a robot claw 54 , a lateral moving motor 55 , a vertical moving motor 56 and a dustproof plate 57 .

[0068] One side of the robot arm bracket 51 is installed on the support base 10, and the other end can be installed on the equipment for processing the workpiece 60. The beam 52 is fixedly installed on the upper end of the robot arm bracket 51, and the horizontal moving motor 55 and the vertical moving motor 56 are both movably installed on the horizontal beam 52. The horizontal moving motor 55 can drive the vertical moving guide rail 53, the mechanical claw 54 and the horizontal moving motor 55 to move on the horizontal beam 52, and the vertical moving motor 56 can drive the mechanical claw 54 to move on the vertical moving guide rail 53.

[0069] When in use, the feeding cylinder 42 is actuated to push the workpiece 60 into the mechanical claw 54, and then the vertical moving motor 56 is started to drive the workpiece to move to a set position in the vertical direction, and then the horizontal moving motor 55 is started to send the workpiece 60 to the specified position. The dustproof plate 57 is sleeved on the upper end of the vertical moving guide rail 53, which can prevent dust from entering the mechanical arm assembly 50.

[0070] like Figure 5 As shown, as another preferred embodiment of the present invention, the mechanical claw 54 includes a clamping claw 541 , an adjusting block 542 , a sliding block 543 and a connecting block 544 .

[0071] The upper end of the connecting block 544 is mounted on the lower end of the vertical movable guide rail 53, the slider 543 is slidably mounted on the lower end of the connecting block 544, the adjusting block 542 is mounted on the lower end of the slider 543, the clamping claw 541 is detachably mounted on the lower end of the adjusting block 542, the clamping claw 541 is composed of two identical clamping claws 5411, and the distance between the two clamping claws 5411 can be manually adjusted to adapt to workpieces 60 of different diameters. Preferably, a plurality of adjusting grooves 5421 are provided at the lower end of the adjusting block 542, and a plurality of adjusting protrusions 5412 are provided at the upper end of the clamping claw 541, and the adjusting protrusions 5412 are clamped in the adjusting grooves 5421. The arrangement of the adjusting grooves 5421 and the adjusting protrusions 5412 can also make the adjustment of the clamping claw 5411 more accurate.
